At the Switch
Three-wire switches will have either a constant ground input or a constant (+)12V input, along
with the pulsed lock and unlock outputs to the factory relays.
Some vehicles have no external switch. The switches are inside the actuator, and instead of
pulsing, the proper wires will flip-flop from (+)12V to (-) ground as the door locks are operated.
Direct-wired switches will have a (+)12V constant input and one or two (-) ground inputs, along
with two output leads going directly to the lock motors.
Type A: Positive-Triggered, Relay-Driven System
IMPORTANT! The H2/A and H2/B wires are not required for wiring the door locks. For
detailed wiring instructions for these two wires, refer to the beginning of the Door Lock
Harness (H2) Wire Connection Guide section. Depending on the type of door lock system,
there may be additional H2 harness wires that are not used for wiring the door locks.
